MARTIN MONTANER, OF PALAMOS, SPAIN.

CORK STOPPER.

SPECIFICATION forming part of Letters Patent No. 768,391, dated August 23, 1904.

Applioationiled March 3, 1904:. Serial No. 196,371. (No model.)

To all whom it may concern:

Be it known that I, MARTIN MONTANER, a subject of the King of Spain, residing at Palamos, Spain, have invented certain new and useful Improvements in Cork Stoppers, of which the following is a speciiication.

In consequence of the increasing diiiiculty of obtaining corks for stoppers of av homogeneous nature it has been proposed to make corks of a combination of natural cork and cork compound, the body of the cork being' made of the cork compound, while the base or part which is next the liquid in the bottle is made of natural cork.

My invention relates to such combined corks, and the novelty resides in the means for joining the said two parts together, so as to form a connection that is both strong and simple in execution. The improved joint is formed on the principle oi' mortise and tenon, for which purpose I form on the base of natural cork a cylindrical tenon having a central cylindricalv recess, so that the tenon is Ofannular shape. In a corresponding manner I form the end of the body of cork compound a cylindrical mortise adapted to receive the tenon, in the center of which mortise projects a cylindrical stud adapted to fit into the recess of the tenon, so that practically the annular tenon of the base iits into an annular mortise of the body. By thus causing a part of the base to penetrate into the body and part of the body'to penetrate into the basev a kind of double joint is'formed,which, with the intervention of a cementing medium, constitutes a very strong connection of the two parts,which' is oi' simple construction and renders the dovetailor other keying connections unnecessary.

The construction of a cork according to my above-described invention is shown on the accompanying drawings, in which- Figure 1 shows a vertical section, and Fig. 2 an end view of the body, while Fig. 3 shows a vertical section, and Fig. 4 an end view of the base. Fig. 5 shows the body and base joined together to form the cork.

The body ct, which is of cork compound, has a cylindrical. recess or mortise c formed in it, from the center of which projects a stud CZ, so that the mortise is of annular form. The base b, 'which is of natural cork, is formedl with a cylindrical tenon e, in the center of which is a cylindrical recess f, so that the tenon is of annular for-m adapted to lit into the annular mortise of the body. Thus on-itting the two parts together, as at Fig. 5, with the intervention of suitable cementing material, an eX- ceedingly strong union of the two partsA is effected by reason of the tenon of the base penetrating into the mortise c of the body, while the stud Z of the latter penetrates into the recess f of the former. The cross-hatching indicates the part orl cork compound, while the single hatching indicates the part of natural cork. l

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A stopper composed of two cylindrical solid sections of the same diameter, connected together end to end, one of natural cork and the other of cork compound, one of said sections having an annular tenon engaging an annular mortise in the other section.

2. A stopper composed of an outer section e of cork compound, having in its end an annular mortise e, and an inner section b, oi' natural cork, which has on its end an annular tenon c' which fits into the said mortise e, the two sections being solid and having their end surfaces in contact throughout.

' In witness whereof I have hereunto signed my name, this 15th day of February, 1904, in the presence of two `subscribing witnesses.

MARTIN MONTANEE. i
